Umm, others already mentioned behavior changes involving more vacation and more tanning, but people also changed their diets. Most diets focus on high carb and low fat, which is unfortunate for cancer. Cancer feeds on sugars and many simpler carbs break down to glucose. Additionally, many processed foods contain quite high levels of sugar. When humans were eating less sugar, cancer cells grew more slowly. As others mentioned, cancer tends to be the thing that kills you most slowly, but it still could be delayed a bit.

It’s worth mentioning that some doctors I’ve met have started advocating low-meat keto for their cancer patients, so while I am completely an amateur with health topics, I feel I am on somewhat firm footing here.

I recall reading a recent study (too lazy to look it up, tbh) that showed a link between skin cancer and sunscreen use, so your numbers may somehow support that suspicion.

That link proves that cancer causes sunscreen. See https://xkcd.com/925/

The opposite actually. Having a high latitude, summers are more intense.

But why? Angle of the sun is lower. Sunrays go through more atmosphere. Is it because people are mostly vertical when they are in the sun?

Nvm. I'm dumb.

All those people tanning in the 90s aren’t going to get skin cancer right away - it takes a few decades to catch up.

The Canadian Cancer Society has a UV camera in a box. People stick their head in and it shows the hundred of freckles, blotches, sunspots under your skin you can't see now but will later. Then they ask you to put on sunscreen and where it is on your skin is opaque jet black.

Neat.

"UV Light Camera Development - Cancer Society" [2018] https://www.smiledealers.com/news/uv-light-camera-developmen...

How do I do this at home?

I tried to figure this out a few years ago, but I remain noob. I found stuff like this:

I'd like to use my phone's camera. I once read that cameras now have built-in UV filters. Because voyeurs were taking "naked" pictures at the beach. But I couldn't figure out if I could cannibalize one of my old phones, turning it into a UV camera.

I am surprised about so much cancer and so little environment talk. The reason I don't wear sunscreen and have spent hours looking at ingredients just to buy none is that I don't want to pollute our waters. After tourist season there is a oily film swimming on our Alp lakes. People are literally walking hours enjoying the nature just to pollute the source of all that. These lakes aren't that big. And their fresh wate…

To follow this. Many natural hot springs that are open to the public have a straight up no sunscreen allowed rule. 3 hours into the high desert with no sunscreen and that is how it should be.

Yeah. I'm also gonna call BS on the "tanning salon" thing. If all it took was copious amounts of UV to f you up that bad every white man outdoor laborer in the south would look like Keith Richards by age 30. I'm sure it didn't help but if your body looks like it has X years of wear and tear on it it's because you've put X years of wear and tear on it.

Sunscreen is a scam. Sun is good for you unless you aren't able to tan.

"Nonsmokers who avoided sun exposure had a life expectancy similar to smokers in the highest sun exposure group, indicating that avoidance of sun exposure is a risk factor for death of a similar magnitude as smoking. Compared to the highest sun exposure group, life expectancy of avoiders of sun exposure was reduced by 0.6-2.1 years. "

Hack your own sunscreen: zinc powder, coconut oil, olive oil. I bought a lifetime supply of zinc for $10. It is edible and free of toxic endocrine disrupters. Goal is not to block everything since you need vitamin D.

Care to share your recipe?

The simplest recipe is what I mentioned, but some people use carrot seed oil or other more exotic oils that have natural SPF. I find mixing coconut and olive oil give it the ideal consistency with natural SPF all easily obtainable from any grocery store. The chelated zinc oxide powder is the only thing you probably need to mail order.

> coconut oil, olive oil That's what I would use if I was going to fry myself in the sun, just from the sound of it. Is it safe to use?

The skin is a semi permeable membrane. So I don't put anything on it I am not prepared to eat. I have been using this mix for well over a decade, and ancient civilizations used it for millennia.

This is pretty popular with surfers in Central America. Zinc Oxide cream, like what you use for a baby's diaper rash, is WAY cheaper than sunscreen (Priced high for the tourists), and it's pretty much available at any pañalera (diaper store, if you can believe it, more like what you'd call a 'dollar store' up north with the other things they sell anyways - many small towns have one). It just makes you look like a gho…

Yes it stays atop the skin and reflects rather than absorbing into your skin and bloodstream. It is best for the beach in your non-fancy bikini. Removing it from the skin is done by wiping with a towel rather than soap and water.
